Can I use cv2.putText on a window without an image?

Or is there any alternatives for me to do so? Thanks!

in short, -- NO.

but it's so easy to create an empty numpy array as a background, ....

canvas = np.zeros((200,200,3), np.uint8) <-- ! there you go ! 
cv2.putText(canvas, "helo ;]", .....)
cv2.imshow("X", canvas)
cv2.waitKey()
